Comparison of prenatal and postnatal ontogeny: cranial allometry in the African striped mouse (Rhabdomys pumilio) [PDF]
, 2017 The relationship between prenatal and postnatal ontogenetic allometry is poorly known, and empirical studies documenting prenatal allometry are few, precluding an understanding of changes in growth patterns during life history and their relation to ...

Clade‐wide morphological and functional variation of the sauropsid columella
The Anatomical Record, EarlyView.Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

, 2019 Meaningful laws of nature must be independent of the units employed to measure the variables. The principle of similitude (Rayleigh 1915) or dimensional homogeneity, states that only commensurable quantities (ones having the same dimension) may be ...

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates
The Anatomical Record, EarlyView.Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Sexual dimorphism and inter-individual variation in the rove beetle, Creophilus maxillosus L. (Col: Staphylinidae) [PDF]
Arthropods, 2017 Sexual selection is expected to drive phenotypic differences between conspecific male and females, a widespread phenomenon known as sexual dimorphism. At the same time, individuals may exhibit some degree of intra-sexual variation. We examined the sexual

Biomass estimation as a function of vertical forest structure and forest height. Potential and limiations for remote sensing (radar and LiDAR) [PDF]
, 2011 Forest biomass stock, spatial distribution and dynamics are unknown parameters for many regions of the world. Today’s information is largely based on ground measurements on a plot basis without coverage in many remote regions that are fundamental for the

The Anatomical Record, EarlyView.Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Brazilian Journal of BiologyOntogenetic allometry is the study of how the size or shape of certain structures changes over the course of an animal’s development. In this study, using Huxley's formula of allometric growth (1932), we assessed the changes in the rate of growth of the ...

British Journal of Clinical Pharmacology, EarlyView.While the event‐free survival (EFS) of children treated for acute lymphoblastic leukaemia (ALL) has improved greatly in the last decades, the EFS for patients diagnosed with ALL before the age of one is still under 50%. This outcome further decreases when infants have a rearrangement in the gene encoding histone‐lysine N‐methyltransferase 2A (KMT2A ...
